Graph and Find domain, range, Constant Interval, Increasing Interval and Decreasing Interval. I don't know how to do this please help. g(x)= {5x-1 if x<2
{x-9 if x < 2

Step-by-step explanation:

The graph is attached. You can see that g(x) is defined for every value of x, so the domain is all real numbers.

There is no value of y that cannot be produced by some value of x. Hence, the range is all real numbers.

The lines have an upward slope everywhere, and a zero slope nowhere. There is a downward jump at the point x=2, but a single point does not constitute a "decreasing interval."

So, the function is increasing everywhere except at x=2, where "increasing/decreasing/constant" are not defined. It is not constant or decreasing anywhere.

The notion of "constant, increasing, decreasing" has to do with the sign of the derivative of the function. Generally, the derivative is undefined at a discontinuity, so "constant, increasing, decreasing" will not apply at a discontinuity.
